A man books a taxi for the airport. The taxi arrives, the man loads his luggage and the taxi sets off. Several minutes into the journey the man notices that the driver has taken a wrong turn. He leans forward and taps the driver on the shoulder to correct him. The driver gives out an almighty shriek and rolls the car into a ditch. Trapped in the wreckage the man questioned the driver "what the hell happened there mate?" to which the injured driver replied "I'm really sorry about that but I've been driving a herse for the last 26 years!"
